The primary purpose of a safety valve is the protection of life, property and environment. A safety valve is designed to open and relieve excess pressure from vessels or equipment and to reclose and prevent the further release of fluid after normal conditions have been restored.
There is a number of reasons why the pressure in a vessel or system can exceed a predetermined limit. API Standard 521/ISO 23251 Sect. 4 provides a detailed guideline about causes of overpressure. The most common are:
Each of the above listed events may occur individually and separately from the other. They may also take place simultaneously. Each cause of overpressure also will create a different mass or volume flow to be discharged, e.g. small mass flow for thermal expansion and large mass flow in case of a chemical reaction. It is the user’s responsibility to determine a worst case scenario for the sizing and selection of a suitable pressure relief device.
At Gulf Gate, we stock & supply different type of Safety valve from reputed manufacturers which you need to complete your project & maintenance on time and on budget. In order to ensure the greatest possible plant safety, the analysis of the conditions and requirements of an application and the corresponding dimensioning of a safety valve is crucial. Determining the necessary dimensions and flow cross-section of a safety valve is referred to as “sizing the safety valve”. Numerous parameters are taken into account in this calculation.
